Correct sentence:
The skunk hides behind its stinky cloud.
Is it grammatically correct? Yes — the sentence is correct.
Why it is correct (step by step):
- Capital letter: The sentence starts with a capital letter: "The" — good.
- Subject and verb match: "The skunk" is one animal (singular), so we use the verb "hides" (not "hide").
- Possessive word: "its" shows that the cloud belongs to the skunk. Be careful: "its" (belonging to it) is different from "it's" (contraction for "it is"). Here we need "its".
- Adjective: "stinky" describes the cloud — that is fine and easy to understand.
- Punctuation: The sentence ends with a period — good.
What the sentence means: A skunk makes a smelly spray (a "cloud" of smell) and hides behind that smelly cloud.
Other simple ways to say it:
- The skunk hides behind its smelly cloud.
- The skunks hide behind their stinky cloud. (If there are more than one skunk.)
- The skunk hid behind its stinky cloud. (If you tell it in the past tense.)
Quick practice for you: Try changing the sentence to past tense or make it about two skunks. Write one of those and I will check it!
